大口径钢筒预应力混凝土管的中间试压技术

Intermediate Pressure Test Technology for Prestressed Concrete Cylinder Pipe (PCCP) with Heavy Caliber

结合常州地区供水一期工程介绍了大口径钢筒预应力混凝土管的中间试压技术,它克服了长距离输送管道因试压需间断施工的弊端,使管道间断施工变成连续施工,并减少了预留原土后背给施工造成的麻烦,加快了工程施工进度。

Introduction was given to the intermediate pressure test technology for PCCP in the first phase of water supply project in Changzhou region.The technology overcame the discontinuous construction needed for long distance water transmission pipe due to pressure test,and achieved the continuous construction.It also reduced the trouble for construction incurred by the use of original soil as backing,and thus accelerating the schedule in construction of the project.
